Description

technical field [0001] The invention belongs to the field of agricultural and forestry machinery, in particular to a novel multifunctional agricultural and forestry manipulator. Background technique [0002] Traditional agricultural and forestry manipulators are generally operated manually or semi-manually, with low levels of mechanization, automation, and intelligence, and are greatly affected by environmental factors. It has caused great distress and inconvenience to the staff, and they cannot work effectively, seriously affecting the work efficiency, and at the same time posing a threat to the personal safety of the staff. [0003] The traditional manipulator telescopic arm hydraulic cylinder piston rod is round, and there is a problem of top rotation when telescopic, which is not conducive to the accurate positioning of the manipulator. In the patent of a drill pipe discharge manipulator, patent number CN201320413671.1, a drill pipe discharge Manipulator, drill pipe dis...

Problems solved by technology

[0002] Traditional agricultural and forestry manipulators are generally operated manually or semi-manually, with low levels of mechanization, automation, and intelligence, and are greatly affected by environmental factors. It has caused great distress and inconvenience to the staff, and they cannot work effectively, which seriously affects the work efficiency and poses a threat to the personal safety of the staff.

[0003] The traditional manipulator telescopic arm hydraulic cylinder piston rod is round, and there is a problem of top rotation when telescopic, which is not conducive to the accurate positioning of the manipulator. In the patent of a drill pipe discharge manipulator, patent number CN201320413671.1, a drill pipe discharge Manipulator, drill pipe discharge manipulator includes: base, lifting table, rotary table, telescopic sleeve, telescopic rod, folding arm and mechanical gripper, etc.

The base is fixed on the structural frame under the drill floor, the telescopic sleeve is hinged to the rotary table, and the telescopic rod is hinged to the folding arm. The telescopic and folding linkage is realized through hydraulic cylinder drive. In this patent, a square hydraulic cylinder and telescopic rod are used. Solved the problem of the top rotation of the telescopic arm during the telescopic process, but the piston rod of the hydraulic cylinder is solid and heavy, which is not conducive to the movement and modification of the manipulator
